CORNELIUS VANDERBILT, OF NEW YORK, N. Y.

CONSTRUCTION OF BODY-BOLSTERS FOR RAILROAD-CARS.

SPECIFICATION forming part of Letters Patent No. 710,636, dated October 7, 1902.

Original application filed November 22, 1901, Serial No. 83,262. Divided and this application filed March 12, 1902. Serial No. 97,919. (No model.)

1'0 (all whmn/ it 777 07 concern.-

3e it known that I, CORNELIUS Vnnona mm, a citizen of the United States, and a resident of the city and county of NewYork, borough of Manhattan,and State of New York, (and whose post-office addressis 608 Fifth avenue, in said city,) have inventedcertain new and useful Improvements in the Construction of BodyfBolsters for Railroad-Oars, of which the following is a specification.

My invention has relation to the construction of railroad-cars, and it has special application to cars wherein cylindrical (or other appropriately-formed) tanks are employed for the transportation of oil, grain, 850.; and the special object of my invention is to improve the construction of the body-bolster which enters into and forms part of the car-fraine construction. In devising the structure hereinafter described I have paid special attention to its organization to the end that commercial forms of iron may be largely, if not wholly, employed and wherein the maximum carrying capacity and strength consistent with a minimum amount of weight in the volume of material utilized may be had.

The embodiment of my invention herein illustrated may be advantageously employed in theimproved tank-car and metallic-car c0n struction for which I have applied for Letters Patent on the 22d day of November, 1901, Serial No. 83,262, of which this case is a division; and it resides in the novel features of construction and combination of parts hereinafter described, and finally pointed out in the claims.

In the drawings forming part of this specification, Figure 1 is a plan view of the bodybolster and a portion of a car-frame embodying my invention. Fig. 2 is a side elevation of the latter, partly in section, the section being taken substantially on the line y y, Fig. 1. Fig. 3 is an end elevation of the body-bolster. Fig. is a sectional elevation of the same, taken on the line 2 ,2, Fig. 2. Fig. 5 is a perspective view of one of the bolster verticalplates or wings. Fig. 6 is a perspective view of the bolster and a part ofthe longitudinal sills. Fig. 7 is a like view of the bolster bed-plate. Fig. 8 is a like view of the sill-chair, enlarged. Fig. 9 is a perspective view of a modified form of bolster, only the upper portion being shown; and Figs. 10, 11,

,12, and 13, like views of further modifications.

In the drawings, 1 1 are the longitudinal sills of the body-framing, which, comprising I-beams having the upright webs 2 and top base-flanges 3 at, as in the application before mentioned, extend from end to end of'the frame, there being no sills outside (transversely) of these two.

In plan, Figs. 1 and 6, the bolster forms a lateral channel, the upper edges of which are downwardly depressed or segmentally disposed on lines concentric with the tank (if a circular one is employed) and which bolster forms acradle, in which the tank rests and t0 whichit may be secur'ed.

The bolster comprises, as embodied herein, three parts-the wings 5, each having their upper edges 6 formed on the segment of a circle concentric with that of the tank, when used to support a tank such as shown in the before-mentioned application, and an upwardly and outwardly extending lower edge 7, which allows clearance for the curving of the truck and the bolster side bearings; the channel-iron bed or base plate 8, having a central flat or plain section 9 and outwardly and upwardly converging end pieces 10, bor-. dered at the sides by the upwardly-extending flanges 11; the segmental T-irons or cradle-pieces 12, having a horizontal flange 13 disposed to conform to the curve of the tank course and concentric therewith and the lower pendent intermediate web 14:, and the compression orsill chair 15,havingalowerweb 16, side and end webs 17 and 18, and crosswebs 19,1nerging into an enlargement 20, having an aperture 21.

Instead of using the curved angle-irons 12 to form cradles to directly or intermediately support the tank I can avail myself of the following modifications in whole or in part without departing from the underlying scheme ofconstruction.

In Fig. 9 an inverted channel-iron 22, having its cross-web 23 curved to conform to that of the tank, (or its course,) is setin between the wings 5 and both parts secured together by rivets (or otherwise) passing through the wings and the pendent curved flanges 24. This construction efliciently ties the wings 5 together and forms a cradle, in which the tank may rest.

In Fig. 10 the wings 5 are transversely tied together by an I-beam 25, the curved web 26 of which is horizontally disposed, the curved flanges 27 being riveted to the wings 5.

In Figs. 11, 12, curved angle-irons 28 29 are used to take the place of the T-iron 22, the curved web being adapted to receive the tank and the flange 30 being riveted to the wings 5. The curved angle-irons may be secured on the inside or outside ofthe wings 5, as shown in Figs. 11 and 12, respectively.

In Fig. 13 a substitute for the T-iron 22 is made by riveting two curved angle-irons 31 to the upper edge 6 of the wing 5 by their flanges 32, the horizontal webs of the angleirons being curved.

The parts of the bolsters are assembled, and it may be united to the I-beams or sills l as follows: The plates 5, Fig. 10, have projections 33 extending in the same plane as the body of the plate, and from these projections extend the ears or flanges 34, provided withapertures 35, the location of the projections 3% being such as to permit them to be received within the upper and lower flanges 3 40f the I-beams. Each of the plates or wings 5 are riveted at their lower'edges 7 to the flanges 11 of the base-plate 8 except adjacent the intermediate section 9, the lower edge 7 of the wings 5 having the same upward inclination as said flanges. The'upper curved edge (5 of the wings are secured to the pendent intermediate webs 14L of the segmental T-irons 12, the pendent web 14 being preferably located on the outside of the wings, so as to give breadth to the bearing of the tank thereon, and the said edge preventing dropping of the cradle-pieces if the rivets shear or break. The lower web 16 of the chair or casting is seated within the flanges ll of the base-plate and rests upon the central fiat portion thereof, both parts being provided with holes 36 37, permitting them to be riveted or otherwise secured together, the central portion of the bed-plate having an aperture 38, alining with the aperture 2l in the chair to permit the passage of a king-bolt or other pivoting device, and to the under side of the central portion 9 of the bed-plate is secured a flat plate 39, forming the upper portion of the disk-shaped center-bearing 40, having a king-bolt aperture 41, alining with the apertures 21 38 in the bed-plate and chair.

It is clear that instead of employing the I-beam sills l to tie the wings 5 together laterally thereof this may be accomplished by the channel or I beams 22 25 or in any other desired way and other modifications made in my invention without departing from the spirit thereof.

I claim- 1. A bolster comprisinga flanged bed-plate, plates or wings extending upwardly therefrom and secured to said flanges, and lateral .extensions having upright flanges secured to the upper edges of said plates.

2. A bolster comprising aflanged bed-plate, the intermitted plates or wings extending upwardly from said flanges, the upper edges of the wings being downwardly curved, and downwardly-curved lateral enlargements secured to the curved edges of said plates or wings and extending over the space between the inner ends of the wings.

3. A bolster comprising bed or base plates, the vertical side plates secured to the base member and intermitted between their ends to form an opening therethrough, the segmental cradle-pieces secured to the upper edges of the plates and extending over the opening, combined with the longitudinal sills extending through said opening and beyond the cradle-pieces, and means for securing the bolster to said sills,

4.. The bolster cdmprising the base-plate, the vertically-disposed wings having laterally-disposed flanges, and the segmental cradle-pieces secured to the wings.

5. A bolster comprising the base-plate, having the central flat portion and upwardly-inclined extensions therefrom, the vertical plates secured to the sides of the base-plate, and the segmental cradle-pieces so secured to the u pper edges of the vertical plates or wings.

6. The bolstercomprisinga base-plate, having a central flat portion and outwardly and upwardly inclined ends, vertical plates or wings secured to said inclined ends, and the segmental cradle-pieces secured. to the upper edges of said wings.

7. A bolster comprising a base-plate, the compression-chair, secured centrally thereto, the vertical plates or wings secured to the plates and the segmental cradle-pieces secured to the upper edges of said wings.

8. Abolster comprising a base-plate having flanges vertical plates or wings secured to the said flanges and the segmental cradle-pieces having a depending web secured to the upper edges of said wings.

9. A bolster comprising a flanged baseplate, the vertical wings secured exteriorly to said flanges, and cradle-pieces each having a segmental horizontal web, and a segmental vertical web secured to the side of the vertical wings, the upper edgesof said wings lying within the plane of the horizontal web.
